Question 136

3, 10, 33, 111, 349, 1072, 3252

Solution

Each number is multiplied by 3 and then squares of natural numbers are added.

3 $$\times 3 + 1^2$$ = 10

10 $$\times 3 + 2^2$$ = 34 $$\neq$$ 33

34 $$\times 3 + 3^2$$ = 111

111 $$\times 3 + 4^2$$ = 349

349 $$\times 3 + 5^2$$ = 1072

1072 $$\times 3 + 6^2$$ = 3252
